we do hereby declare that thefollowing, taken in connection with thedrawings which accompany and form part of this specification, is a.

description of our invention suicient to enable those skilled in the artto practice it.

Our invention relates to the formation'of a metal nail-plate blank, foruse in machines' for nailing soles to uppers of boots and shoes. Suchblank we make from a plain ilat strip of metal having a width eqnaltothe maximum length of nails to be formed from it, and this plate,beveled npon one edge,.we form with di?" l visions, spaced in accordancewith .the width each nail is to have, making such divisions preferablyby two blunt-edged chisels or grip-y ers acting against oppositesurfaces ot' the plate.A The action of these gripers. is made to almostseparate each nail, leaving. adja'cet nails united by a slight web, andsothat each nail maybe very easily separated from the l rest of theblank. The gripers are preferably formed .with teeth or'serrations, thatbring up or form slight projeetions'upon the surfaces of the nails.

' The linvention consists'in a nail-blank thus formed from a plate, orametal plate having nail-blanks joined by thin webs of the metal.

The drawing represents ablank embodying our invention.
